8th Science Vocab

Speed The rate at which an object moves
Average Speed Speed=Difference/ Time
Velocity Tells the rate an object moves and in which direction it moves Think of a air traffic controller
Acceleration Change in velocity (speed and direction) and direction of an object **A car going at the same speed but turning*
Force The push or pull between objects
Mass The amount of matter making up an object
Independent Variable What you change in your experiment or it´s the variable that you´re testing
Dependent Variable It´s what we measure: the information you put in the data table *changes the independent variable doesn´t depend on anything else (stands alone)
Inertia 1)The tendency of ALL objects to RESIST a change in motion 2) the MORE mass an object has the the MORE INERTIA IT HAS
Newton's First Law Effect of balanced and unbalanced forces on an object at rest ans on an object in motion
Newton´s Second Law The amount of force needed to accelerate an object. It depends upon a mass of the object.
Mass VS. Weight Mass: Does not change with location Weight: It does change with location. A measure of the force of gravity.
Balanced Forces There is no motion
Unbalanced Forces One side powers the other *So it will move to he side that pushes harder.
Energy Ability to do work or to cause. Exists in many forms.
Frame of reference The point of view which you observe motion Example: ¨You are traveling north and your friend are not moving. That's because you and your friends are in the same reference frame.
Resultant Occurring or produced as a result or consequence of something
Vectors Magnitude & the direction of the force 10 N R (vector)
